Title: Circuit for controlling motor
Inventor: TSURUMI KOJI
IPC: H02P7/29
Filed: 1990-10-18
Abstract: PURPOSE:To improve an efficiency, by controlling the poster supply voltage applied to a DC motor through controlling the pulse width modulation circuit of a switching regulator based on the difference in period between a desired rotational period and the rotational period of the motor, and by removing the margin of the power supply voltage when rotating steadily. CONSTITUTION:Provided are a motor driving circuit 12 which drives a DC motor 10, and a switching regulator 16 which feeds the DC voltage obtained through switching by a pulse width modulation circuit 14, to the motor driving circuit 12 as a power supply voltage. Further, a control signal for the pulse width modulation circuit 14 is generated based on a difference in period  T between a desired rotational period T1 and a rotational period T2 of the motor 10. Then, provided is a control means 18 which reconciles the rotational period of the motor with the desired rotational period by adjusting the power supply voltage for the motor driving circuit 12 through the generated control signal. Here, the control means 18 so operates as to decrease the power supply voltage by generating the control signal, which makes a pulse width narrow, when the difference in period  T is positive and as to increase the power supply voltage by generating the control signal, which makes the pulse width wide, when the difference in period  T is negative.

Abstract: PURPOSE:To obtain a bright, large-aperture-ratio, and long-back-focus Gaussian lens of 1.0 in F number and about 45 deg. in photographic field angle which have aberrations compensated excellently over the entire image plane by specifying the geometric constitution of the lens. CONSTITUTION:The 4th negative lens G4 and the 5th negative lens G5 are arranged across a stop S and part of the negative refracting power that the concave surfaces of the lenses on the side of stop S is put in partial charge of the 2nd negative lens G2 and the 7th negative lens G7 in specific shaped which are arranged newly on the object and image-surface sides of the 4th lens G4 and the 5th lens G5. Thus, the concave lenses of the 4th lens G4 and the 5th lens G5 on the side of the stop S are reduced in negative refracting power to reduce sagittal flare and also reduce sagittal flare of color, principally, (g) rays at the same time. The Petzval's sum which increases when the negative refracting power is weakened is corrected by the 2nd lens and the 7th lens.

Filed: 1989-10-27
Abstract: PURPOSE:To prevent the occurrence of density irregularities to improve an image quality by providing a non-volatile memory element prestoring data representing characteristics intrinsic to an ink delivery part of a head or data for correcting said characteristics. CONSTITUTION:On a printed board 1 containing heating elements and a drive control part in an ink jet recording head, an EEPROM 4 for recording information of density irregularities intrinsic for every recording head is mounted. The density irregularities for every head are measured when the head is produced. Based on the measured data, for every delivery port or group of some delivery ports, data of density irregularities corresponding to the delivery port or delivery port group or data for correcting the density irregularities are recorded on the EEPROM 4, for example, at the production of the head. In this manner, when the recording head is loaded on a main body device, the main body device reads information related to the density irregularities from the recording head and on the basis of this information conducts a predetermined control for improving the density irregularities to ensure a good image quality.

Title: Rotation of wave face for shearing interference measurement
Inventor: BANBA NOBUO
IPC: G01B9/02
Filed: 1988-11-07
Abstract: PURPOSE:To perform lateral shifting of a wave face easily or accurately in a direction orthogonal to each other with a simple mechanism by turning a wave face rotating element as disposed by at a front stage of a wave face division element 45 deg. about an axis parallel with an optical axis of an incident light. CONSTITUTION:When an incident luminous flux having a wave face W to be measured is incident, the luminous flux is reflected with reflecting mirrors 10, 12 and 14 composing a wave face turning element to be emitted. When an optical axis beam is indicated by the arrow F1 while other lights by the arrow F2, a direction of the wave face W to be measured is specified by a relationship of the beams F1 and F2. When a luminous flux is emitted from the wave face turning element, a direction thereof is turned about the beam F1 by 180 deg. from the direction thereof when being incident. When the whole of the wave face turning element is turned by 45 deg. about the beam F1 from this state, the direction of the wave face of the outgoing luminous flux is turned by 90 deg. from the direction thereof before the turning of the wave face turning element. Thus, wave faces W to be measured in a relationship of being turned by 90 deg. from one to the other can be made incident sequentially to a wave face division element thereby enabling lateral shifting of wave faces divided in a direction orthogonal to each other with the turning of the direction of the wave faces W to be measured themselves by 90 deg..
